Eastwood Towne Center is an open-air shopping center on Lansing's east side, built to feel more like a downtown street than a mall. National retailers like Barnes & Noble, Dick's Sporting Goods, and Old Navy line pedestrian-friendly walkways, and the dining options -- Bravo! Italian Kitchen, Biggby Coffee, and a handful of fast-casual spots -- make it a reasonable lunch stop if you are in the area. There is a cinema on site too.
It is not a destination in itself, but if you need to shop while in the Lansing area, this is the most pleasant option.
